Modeling the hybrid seedling performance of forage sorghum and silage corn under Jordan irrigation conditions

Abstract

The beta casein gene (CSNS2) has 12 genetic variants divided into two groups: the first group (A1, B, and G) which differ from the second group (A2, A3 C, D, E, F, H, H2 and I) where A base replaces C base, this leads to potential liberation of a bioactive peptide, b-casomorphin, upon digestion where a histidine replaces a proline at position 67. The allele specific polymerase chain reaction (AS-PCR) was evaluated to distinguish between the beta casomorphin releasing variants (A1 and B) and the non-releasing variants. The sequence analysis was used to determine these variants and confirm it in goat, sheep and cattle. The results showed that cattle carrying allele A1 either homozygous or heterozygous more than sheep and goats. The allele frequency of A1 and A2 is 0.44, 0.56 in goats, 0.43, 0.57 in sheep and 0.54, 0.46 in cattle, respectively. The sequence results reported changing of C base to A base in goat, sheep and cattle. Therefore, this study reported that goat and sheep milk was more safe than cattle milk.

Economic Analysis for Forage Agronomic Crops Grown Using Treated Wastewater in Kherbeh Als-Samra Region, Jordan

“…Climate change indicated that the productivity of forage crops is highly variable in simulated extreme drought conditions of Jordan, where rainfall or irrigation amounts and distribution are highly variable. [13] reported that selection of specific drought-tolerant hybrid of silage corn seeds in Jordan would be an efficient and useful method of improving uniformity, water use efficiency, and providing superior seedling performance with the potential for improved vegetative yields under extreme drought conditions of Jordan. The costs of agricultural mechanization and hand labor are very important in the production of forage crops in Jordan.…”
